Auto enumerate on file name collision

[Rohan2460]

When file name collision occurs it should auto enumerate the file names
Format example:
File_name (1).txt
File_name (2).txt

I believe it already does this...

There's a little hint in the "rename" window that you can attach a %n to your rename, and it'll enumerate for you.

Not sure if this is what you're asking for or not (I was looking for a different feature)
